On OS X, .pyw is not normally used as an extension for Python files.  
There is actually no difference between python and pythonw on OS X.   
That said, the simplest way to change the application association for a 
file extension on OS X is to select (single-click) on the file in the 
Finder, then select Get Info (from the Finder File menu or type CMD I).  
In the Info window that opens, if necessary, click on the disclosure 
triangle next to "Open with" and then select the application you want to 
use.  Most likely the choices will be several versions of IDLE and 
possible several versions of Python Laucher (a simple launcher app 
included with the python.org distributions).  If you always want to use 
that app for all files with that extension, click the "Change All..." 
button as well.
